noteworthy Astragalus observations

September, 2023
Tentative ID of Astragalus argophyllus in Yavapai County, Arizona.

see my comments here:
other observations of this taxon: (further south, but with characteristic silky pods) (sterile, but shows distinct stipules) (sterile)

December, 2022
Astragalus lentiginosus var. lentiginosus in Nevada County, California:
this observation is probably the same thing, but lacks pods:
note that I first thought this was var. salinus but changed my mind based on the prostrate habit and the earlier observation.

Astragalus regiomontanus from Tamaulipas - apparently only documented for Nuevo Leon - considered endemic to that state in

October 12, 2022
Astragalus robbinsii from Olympic National Park.
observed in 2023 - with glabrous pods!

Astragalus cibarius from New Mexico.
No collections in Seinet. Barneby (1964)maps a collection that is close to this one in southeast San Juan county (and another in west central NM) but does not include NM in his written description.

Astragalus gibbsii from Douglas County, Nevada. No previous county record found.
the second observation is more prostrate than usual, but accounted for in Barneby's description
No records of any Astragalus collections in CCH2 or Seinet from Genoa Peak east of Lake Tahoe - appears to be a very poorly collected location. TIL Carson City was in Ormsby County until 1969, now it is an independent municipality, but considered Carson county for census purposes.

September 7, 2022
Astragalus proximus in Cibola County, New Mexico. No previous county record found, and a range extension of ca. 40km to the south. But the Navajo Nation is very poorly represented in herbarium databases, so likely more widespread in the area.

July 26, 2022
Astragalus tioides - perhaps the first record from Guanajuato?

June, 2022
Astragalus brauntonii in Baja California! Also, a potential new species...

March, 2022
Astragalus agnicidus in Santa Cruz county, California!

Sept, 2021
Astragalus wardii documented for Arizona.
see comments from @walterfertig on the observation.

June, 2021
Astragalus congdonii in Shasta County, California
range extension of ca. 200 miles from Amador county
is this an introduction or natural occurrence?

April, 2021
Astragalus newberryi var. escalantinus in Arizona (Grand Canyon National Park)
there is an earlier herbarium specimen from Grand Canyon NP

December, 2020
Astragalus lentiginosus var. sierrae in Riverside county.

March, 2020
Astragalus mollissimus documented for Idaho.
There is a herbarium specimen from 1998, but it is was identified by Welsh as A. purshii and not included in his FNA treatment.
